VFR for 500
The Mode-C part of your transponder (altitude reporting capability) is not functioning and you need to fly to another airport for repairs. Your route will take you over the Tucson airport (KTUS), whose Class C airspace extends up to 6,600 MSL. You plan to fly eastbound at 9,500 MSL, VFR. This operation is legal as long as you remain above the Class C airspace and below 10,000 MSL. True or False?
False. FAR 91.215(b) states that your transponder's altitude reporting feature must be operational and turned on not only within Class A, B, and C airspace; within 30 NM of an airport with Class B airspace, when above 10,000 MSL; but also "in all airspace above the ceiling and within the lateral boundaries of a Class B or Class C airspace".
FAR 92.215(b)(4)
